Analysis of Draft Regulations on Forecasting and Scheduling of Wind and Solar Generating Stations – Rajasthan

CERC had notified forecasting and scheduling (F&S) regulation for inter-state sale of power a few months back. Subsequently, the Forum of Regulators (FoR) had come up with model regulations for forecasting and scheduling at the intra-state level. Rajasthan has published the draft forecasting and scheduling regulations

in line with the FoR model Regulations. Rajasthan is the fourth state to do so in recent days – MP, Karnataka and Tamil Nadu are the others.

Executive Summary:

The regulations will be applicable on all wind and solar generators with individual or combined capacity of 5MW and above that are connected to the state grid

Deviation will be calculated on the basis of available capacity

Settlement with the buyer will be on the basis of actual generation

Qualifying Coordinating Agency (QCA) will play a key role in the total process. QCA will be responsible for forecasting, telemetry, scheduling and settlement of deviation.

The draft regulations are in-line in every aspect with the model F&S regulations released by FoR earlier. However, the model FoR regulations had proposed a 10% deviation band for new projects and 15% for existing projects. Rajasthan has proposed a 15% band for all projects.

Detailed Analysis:

Forum of Regulators have recently come up with model regulation for forecasting and scheduling and deviation settlement mechanism. The primary objective is two fold :
